When Emerson first pioneered the use of scroll technology in compressors, it changed the industry forever. Since then, Copeland Scroll™ technology remains at the forefront for Comfort and Refrigeration applications, impressing contractors and original equipment manufacturers (OEMs) with its superior efficiency, proven reliability and ease of installation.

The Copeland Scroll compressor has one scroll, or spiral, orbiting in a path defined by a matching fixed scroll. The fixed scroll is attached to the compressor body.

The orbiting scroll is coupled to the crankshaft and orbits, rather than rotates. The orbiting motion creates a series of gas pockets travelling between the two scrolls. On the outer portion of the scrolls, the pockets draw in gas, which they then force to the centre of the scroll, where the gas is discharged. As the gas moves into the increasingly smaller inner pockets, the temperature and pressure increase to the desired discharge pressure.

Design Benefits

Better Liquid HandlingAxial and radial compliance allow the scroll members to separate in the presence of liquid refrigerant, thus, providing protection against liquid damage and compressor superior robustness and reliability.

Greater EfficiencyMore efficient over their entire operating range

Unmatched Reliability

70% fewer moving parts then other compression technologies

Ability to start under any system load, without start components

Easy to service and maintain due to their compact size and lightweight, simple design
